Diaphram Type Dosing Pumps are recommended for hazardous, toxic and Poisonous liquids, where leakage is not at all permitted. Diaphragm pumps have hydraulically actuated diaphragm and a back pressure valve. The main function of back pressure valve is to balance the hydraulic oil in the chamber.

The reciprocating plunger transmit displacement through hydraulic oil to the diaphragm, the oscillation of diaphragm produces pumping action on process fluid with help of Non-Return Valve in built at both ends. The diaphragm acts as a perfect seal between the hydraulic oil and the liquid being pumped. Diaphragm pump can be provided with single or double diaphragm; usually Teflon acts as a diaphragm. The back pressure valve which is in the hydraulic oil tank ensures pumping accuracies for long period. The pressure drop in hydraulic chamber due to oil leakage is automatically compensated by opening back pressure valve. Besides back pressure valve acts as safe guard from damages if discharge pressure exceeds pump rated pressure.

Jaz Diaphragm type dosing pump are the sturdily constructed dosing pumps widely used in a number of industries. These are leak proof and widely used for highly aggressive or toxic media. Technically advance range of these pumps is fitted with a separation chamber as standard, which protect its medium from flooding the system components or the pump itself in the situation of crack. Besides, these medium sides of this diaphragm are coated with PTFE to ensure safe usage. These are engineered from high quality components and following international industrial standard.

Diaphragm type dosing pumps are widely used in various industries for metering and dosing of chemicals and other fluids. Mumbai and India have many manufacturers who specialize in the production of diaphragm type dosing pumps. Among these manufacturers, Jaz Pumps stands out as a leading brand, offering high-quality pumps that are reliable and durable.

JAZ Diaphragm type dosing pump consists of three main devices
1. driving device
2. adjusting device
3. liquid delivery device.

The crankshaft which reduces motor rotation speed by worm and worm gear makes the piston reciprocate in the hydraulic oil chamber. This reciprocating movement of the piston makes the PTFE diaphragm and the liquid which is isolated by the diaphragm sucked and discharged. Each pump is with internal pressure relief valve protecting pump from over pressure conditions.

The flow rate can adjusted via unique adjusting mechanism from 0-100%. The adjustment can be carried when pump is in operation or at stop. The steady sate accuracy is ±1% from 30%-100% of the maximum output. Automatic operation is achieved by variable speed drive.

JAZ Diaphragm type Dosing pump are capable of dosing corrosive, vaporing, flammable, explosive or toxic solutions. It can also transport suspended liquid or moderately viscous liquid. Double diaphragm with diaphragm rupture detecting system is available to prevent accident caused by mixture of hydraulic oil and the liquid after diaphragm ruptures.


This equipment is suitable for ordinary normal temperature water and other liquids even with strong corrosion, volatile, easy crystallization flammable, explosive, highly toxic, corrosive, radioactive or valuable characteristics. It can also transport suspensions. In order to prevent accidents caused by the mixture of medium and hydraulic oil in case of diaphragm rupture, metering pump with double-diaphragm and diaphragm rupture alarm system can be chosen for the transportation of inflammable, explosive, highly toxic and valuable liquids.
